Biochar concrete and preparation method thereof
The invention discloses biochar concrete and a preparation method thereof. The biochar concrete is prepared from the following components in parts by mass: 0.5 to 0.6 part of water glue, 260 to 280 parts of water, 500 to 550 parts of cement, 400 to 450 parts of sand, 300 to 320 parts of coarse aggregate a, 700 to 730 parts of coarse aggregate b, 3 to 3.6 parts of a water reducing agent and 30 to 200 parts of biochar. Compared with the prior art, the method has the advantages that the charcoal cracked by three-phase electric furnace high-temperature cracking replaces fine sand in concrete production for filling, so that the breaking strength, compressive strength and self-constriction of the concrete can be greatly improved, and meanwhile, the production cost can be reduced.
本发明公开了一种生物炭混凝土及其制备方法，它包括质量比为水胶0.5份‑0.6份，水260份‑280份，水泥500份‑550份，砂400份‑450份，粗骨料a300份‑320份，粗骨料b700份‑730份，减水剂3份‑3.6份，生物炭30份‑200份。本发明与现有技术相比的优点在于：本发明通过三相电炉高温裂解裂解出的生物炭替代混凝土生产中较细的砂进行填充，可以大大提高混凝土的抗折强度、抗压强度和自收缩性，同时可以降低生产成本。
